parts of other electrical appliances such as a lamp, TV set etc.

CAUTION

POWER LINES

Any outdoor antenna must be located away from all power lines.

OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tuner-

preamplifier, be sure the antenna system is grounded so as to

provide some protection against voltage surges and built-up static

charges. Article 810 of the National Electrical Code, ANSI/NFPA No.

70-1984, provides information with respect to proper grounding of

the mast and supporting structure, grounding of the lead-in wire to

an antenna discharge unit, size of grounding conductors, location of

antenna discharge unit, connection to grounding electrodes and

requirements for the grounding electrode.

a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2)

aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze

wire, or larger, as a ground wire.

b. Secure antenna lead-in and ground wires to house with stand-off

insulators spaced from 4-6 feet (1.22 - 1.83 m) apart.

c. Mount antenna discharge unit as close as possible to where lead-

in enters house.

d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper,

or the equivalent, when a separate antenna-grounding electrode

is used. see NEC Section 810-21 (j).

REMOTE CONTROL

QUICK START

Use the RCA-to-RCA lead to connect the S400 left & right outputs to

the tuner inputs of your amplifier.

1. Plug in the AC Mains cable.

2. Connect FM antenna.

3. Connect S400 outputs to amplifier.

4. Press the POWER button to turn on the S400.

5. Select antenna input to which aerial is connected.

6. Press TUNE

for one second to activate Search mode.

7. When a station is found, search will stop.

NOTES ON INSTALLATION

Your S400 should be placed on a firm, level surface. Avoid placing

the unit in direct sunlight, near sources of heat and damp or in

poorly ventilated positions.

It comes with RCA leads for connection to your amplifier. Ensure that

leads and connectors are not damaged in any way and all connectors

are firmly pushed home.

If the unit is not going to be used for some time, disconnect the plug

from the AC socket.

Should water get into your S400, shut off the power to the unit

and remove the AC Mains cable from the AC socket. Have the

unit inspected by a qualified service technician before attempting

to use it again.

Do not open the tuner or attempt to modify or repair it

yourself. Refer all servicing to a qualified technician. Do not

remove the cover, there are no user-serviceable parts inside.

Use a dry soft cloth to clean the unit. If necessary, lightly dampen the

cloth with soapy water. Do not use solutions containing benzol or

other volatile agents.

REAR PANEL CONNECTIONS

1. FM ANTENNA

The S400 is equipped with two antenna connectors to allow you to

connect simultaneously to for example a cable network and an

outdoor aerial.

A ribbon wire FM antenna is included in order to permit reception

even if no outdoor antenna or cable is available. It should be

connected to one of the FM connectors at the rear of the unit using

the `balun' adapter supplied. See Figure 1.

The ribbon aerial should be mounted on a vertical surface and placed

so that it forms a `T'. Experiment with placement of the indoor

antenna to find the position that gives the best signal strength and

lowest background noise. An inadequate FM signal normally results

in high levels of hiss, especially in stereo, and interference from

external electrical sources. In areas of poor FM reception, the tuner

performance can be improved by using an externally mounted FM

antenna. A qualified aerial installer will be able to advise and fit a

recommended aerial for your reception conditions.

2. OUTPUT

Using twin RCA-to-RCA leads, connect the Left (white) and Right

(red) audio outputs to the `Tuner' input or other line-level input such

as `Aux' input of your amplifier.

3. NAD-LINK IN/OUT

The NAD-Link connector is used to pass commands from other units

fitted with NAD-Link connectors. This allows centralised control of a

complete system, and also allows some of the basic functions of the

S400 to be controlled using a NAD-Linked amplifier's remote control

or gives system control from more than one room. To function with

such other units, connect the Tuner's NAD-Link IN to the NAD-Link

OUT on the other unit. NAD-Link connectors can be daisy-chained,

IN to OUT, so that a whole system can be controlled from the remote

control facilities of one unit.

4. IEC AC MAINS INPUT

The S400 comes supplied with a separate AC mains cable. Before

connecting the cable to a live wall socket, ensure that it is firmly

connected to the NAD S400's AC Mains input socket first. Always

disconnect the AC mains cable plug from the live wall socket first

before disconnecting the cable from the S400 Mains input socket.

FRONT PANEL CONTROLS

1. POWER ON/OFF

Press this button to switch on the power to the S400. Press again

and release to switch the power off. The display window lights up

when power is ON. The blue LED above the POWER button lights up

briefly when ON/OFF is activated, but it goes out again immediately.

The blue LED lights up permanently only to indicate stand-by if the

unit is turned off from an NAD system remote control with STANDBY

button. If this option is used, the S400 may be switched on again by

pressing the STANDBY button of the system remote, or by pressing

and releasing the POWER button on the front of the S400 to switch

it off, and then press it again to switch it on. Please note that the

remote control which comes with the S400 does not feature a

STANDBY button.

The S400 uses a non-volatile memory to store preset information.

This information is retained even if the unit is switched off

completely or unplugged.

NOTE: When switching power On, the S400 will go back to the

station last tuned to before the unit was turned off. This will allow

you to make timer recordings using an external timer and recorder.

2. MONO/MUTE

Switches between Stereo mode with Muting (Mute) on and Mono

mode with Muting off. Muting suppresses stations that are too weak

to be received well. If Muting is switched off, even very weak

stations may be heard. As these will always be too weak for stereo

reception, Mono is activated simultaneously. The first press of the

button shows Mute On or Off as well as Stereo or Mono in the

display panel. Press Mute again within approx. five seconds to turn

Muting off (or on) and at the same time switch from stereo to mono.

NAD S400 RDS FM Tuner

3. BLEND

High Blend is used for stations that are too remote or weak to permit

noise-free reception in stereo. In order to reduce noise and hiss, this

feature "blends" the stereo channels into mono within a narrow

audio frequency band, thereby reducing hiss considerably while still

maintaining good stereo separation. Pressing BLEND first shows the

status in the display panel. Pressing again within approx. five seconds

changes to ON or OFF.

4. IF

Intermediate Frequency control. Changes the IF between two values,

WIDE for the best possible sound quality and NARROW to remove

interference between stations that are very close to each other in

frequency. Pressing IF first shows the status in the display panel.

Pressing again within approx. five seconds changes to NARROW or

WIDE.

5. ANTENNA

Switches between one of the two antennas that may be connected

to the S400. Pressing ANTENNA first shows the status in the display

panel (Antenna 1 or 2). Pressing again within approx. five seconds

cycles between the two. Simultaneously, the signal strength for the

current antenna is shown as "S" and 0 to 9, where 0 is minimum or

no signal and 9 is maximum signal strength.

6. PRESET (230V VERSION)

OR MODE (120V VERSION)

The PRESET (or MODE) button switches between two ways of using

the TUNE buttons

Press the PRESET (or MODE) button until the "PRESET" LED lights up.

Press the

button to scroll to a lower number preset. Press the

button to scroll to a higher preset number. A total of 30 preset

memories are available. This is a "wrap-around" function, so that

going from the highest number preset the tuner will go to the

lowest preset number when

is pressed.

Refer to section 10. STORING AND RECALLING PRESETS.

NOTE: In the 120V North America version of the S400, which is not

equipped with RDS, the PRESET button is named MODE. It switches

between the Preset and Search functions indicated by the PRESET

and SEARCH LED's lighting up alternately.

7. LED INDICATORS

The PRESET indicator is explained under section 6. PRESET.

The RDS indicator lights up when a station broadcasting RDS data is

received.

The SEARCH indicator lights up (in 120V version only) when the

S400 is in Search mode.

The STEREO indicator lights up when the S400 receives a stereo

broadcast.

The CENTRE TUNE indicator lights up when the S400 is tuned to the

exact frequency of the transmitter.

8. DOT MATRIX DISPLAY AND DISPLAY BUTTON

The display is the centre of information. It is controlled by the

DISPLAY button, which allows you to read out various details about

the broadcasts.

1. When the S400 is switched on, the display shows the frequency,

the signal strength and the Preset number (if any).

2. After 3 seconds, the display switches to RDS station name and

frequency, or manually entered name. If there is no RDS data or

name, the display remains as a).

3. If the DISPLAY button is pressed, the display shows RADIO TEXT if

the station features this.

4. Pressing the DISPLAY button once more changes back to 1.

5. If the DISPLAY button is pressed and held down, the display will

scroll through the above information followed by all setup details

for Mute, IF, Antenna and Blend. Each line is shown for 2 seconds.

9. STORE

The STORE button is used to store stations into the Preset Memory.

Used in conjunction with the PRESET (or MODE) and TUNE buttons.

10. TUNE

AND

The function of these buttons depends on the tuning mode

indicated in the display panel.

In normal operation there are 2 modes:

a) Preset mode Press the PRESET (or MODE) button until the

"PRESET" LED lights up. See section 6. PRESET.

b) Search mode Press the PRESET(or MODE) button until the

"PRESET" LED extinguishes (or in 120V versions, until the SEARCH

LED lights up).

Now you can use the TUNE buttons

to engage

automatic or manual tuning up or down the frequency band.

Auto By keeping one of the TUNE buttons depressed for more than

approx. one second and then letting go, the tuner will search

automatically for the first reasonably strong radio station, where it

will stop. Press and hold the TUNE button again to start searching

again. If a stereo station is received, the "STEREO" LED will light

up.

Manual By tapping one of the TUNE buttons

rapidly,

you can perform manual tuning up or down the frequency band

for precise tuning to a specific frequency. With each successive tap

of the keys, the tuner will take 0.025MHz steps on so you can

accurately tune into the desired frequency. This tuning mode can

also be useful when trying to receive a radio station, which is too

weak for the Search mode.
